<h1>This is a heading</h1>
<h2>This is a heading</h2>
<h3>This is a heading</h3>
<h4>This is a heading</h4>
<h5>This is a heading</h5>
<h6>This is a heading</h5>
Paragraphs.
<p>This is paragraph</p>
<p>This is text paragraph</p>
Line Breaks
The <br> tag is used when you want to break a line. The <br> tag forces a line break wherever you place it.
